i roll mon-wed-fri and do 1.5 hours of liss sun-tues-thurs. current rhr is 65-60 bpm. was at 57 saturday. been as low as 55. i can switch this to bjj training monday-friday with liss on sunday, if need be. my goal is to become better at bjj. BUT i also want a better gas tank, in general. is this counter-intuitive? will the hard rolls from bjj negate the effects of cardiac output training? thanks in advance.
